#ifndef VM_H
#define VM_H
#include "zstring.h"
- started with cleanup and separation of DECORATE code. * everything related to scripting is now placed in a subdirectory 'scripting', which itself is separated into DECORATE, ZSCRIPT, the VM and code generation. * a few items have been moved to different headers so that the DECORATE parser definitions can mostly be kept local. The only exception at the moment is the flags interface on which 3 source files depend.

The current exception mechanism is still insufficient. It really has to report a proper crash location and print a stack trace to the maximum extent possible. Instead it just prints a message and happily goes on. This is not a good solution.

#include "doomerrors.h"
- took VMFunction out of the DObject hierarchy. As it stood, just compiling the internal ZScript code created more than 9000 DObjects, none of which really need to be subjected to garbage collection, aside from allowing lazy deallocation. This puts an incredible drag on the garbage collector which often needs several minutes to finish processing before actual deletion can start. The VM functions with roughly 1800 of these objects were by far the easiest to refactor so they are now. They also use a memory arena now which significantly reduces their memory footprint.

- Turned DropItem into a plain struct again like it was before the scripting branch got merged. Making this an object had little to no advantage, except being able to remove the deleter code. Now, with some of the class data already being allocated in a memory arena so that freeing it is easier, this can also be used for the drop item lists which makes it unnecessary to subject them to the GC. This also merges the memory arenas for VM functions and flat pointers because both get deleted at the same time so they can share the same one.

- implemented passing vectors as parameters. So far working for native functions. - removed the bogus optional value from the first A_Jump argument. A quick test with an older ZDoom revealed that this was never working - and implementing it would make things a lot more complicated, especially error checking in the code generator. - fixed: The check for insufficient parameters to a function call was missing.

class CVMAbortException : public CDoomError

static FString stacktrace;
redid the exception mechanism for script-side access violations to be of more use for diagnosing problems. The original implementation just printed a mostly information-free message and then went on as if nothing has happened, making it ridiculously easy to write broken code and release it. Changed it to: * Any VMAbortException will now terminate the game session and go back to the console. * It will also print a VM stack trace with all open functions, including source file and line numbers pointing to the problem spots. For this the relevant information had to be added to the VMScriptFunction class. An interesting effect here was that just throwing the exception object increased the VM's Exec function's stack size from 900 bytes to 70kb, because the compiler allocates a separate local buffer for every single instance of the exception object. The obvious solution was to put this part into a subfunction so that it won't pollute the Exec function's own stack frame. Interesting side effect of this: Exec's stack requirement went down from 900 bytes to 600 bytes. This is still on the high side but already a lot better.

- stop using the ATAGs for checking pointer types in asserts. This is an incredibly costly way to do a debug check as it infests the entire VM design from top to bottom. These tags are basically useless for anything else but validating object pointers being passed to native functions (i.e. mismatches between definition and declaration) and that simply does not justify a feature that costs execution time in non-debug builds and added memory overhead everywhere. Note that this commit does not remove the tags, it only discontinues their use.

class VMFunction
- actually evaluate the default parameters and store them in the VMFunction. - disabled the assert in PType::GetRegType. This assert blocks any use to check for types that are incompatible with function parameters. - pass the default parameter constants to the native functions. At the moment this is not used yet. - use the function defaults to complete argument lists to script functions. - fixed all default values that got flagged by the expression evaluator as non-constant. Most were state labels and colors which were defaulted to "". The proper value is null for states and 0 for colors. - also replaced all "" defaults for names with "none".

- disabled the scripted virtual function module after finding out that it only works if each single class that may serve as a parent for scripting is explicitly declared. Needless to say, this is simply too volatile and would require constant active maintenance, not to mention a huge amount of work up front to get going. It also hid a nasty problem with the Destroy method. Due to the way the garbage collector works, Destroy cannot be exposed to scripts as-is. It may be called from scripts but it may not be overridden from scripts because the garbage collector can call this function after all data needed for calling a scripted override has already been destroyed because if that data is also being collected there is no guarantee that proper order of destruction is observed. So for now Destroy is just a normal native method to scripted classes

- took VMFunction out of the DObject hierarchy. As it stood, just compiling the internal ZScript code created more than 9000 DObjects, none of which really need to be subjected to garbage collection, aside from allowing lazy deallocation. This puts an incredible drag on the garbage collector which often needs several minutes to finish processing before actual deletion can start. The VM functions with roughly 1800 of these objects were by far the easiest to refactor so they are now. They also use a memory arena now which significantly reduces their memory footprint.

- Turned DropItem into a plain struct again like it was before the scripting branch got merged. Making this an object had little to no advantage, except being able to remove the deleter code. Now, with some of the class data already being allocated in a memory arena so that freeing it is easier, this can also be used for the drop item lists which makes it unnecessary to subject them to the GC. This also merges the memory arenas for VM functions and flat pointers because both get deleted at the same time so they can share the same one.

The allocation overhead doubles the time to set up the call. With one stack, previously allocated memory can be reused. The only important thing is, if this ever gets used in a multithreaded environment to have the stack being declared as thread_local, although for ZDoom this is of no consequence. - eliminated all cases where native code was calling other native code through the VM interface.

- added null pointer validation to any relevant exported function. In most cases null pointers were already being treated as 'do nothing', but there's several places where this can make the code silently fail so in these cases a VM exception will be raised, once the VM's exception handling has been repaired to provide useful diagnostics. (Right now all it does is catch the exception, print a useless message and return to the caller as if nothing has happened.)

- implemented the backend for dynamic arrays. Still needs thorough testing but it should be complete. - use a memory arena to store flat pointers so that the messed up cleanup can be avoided by deallocating this in bulk. - added a new SO opcode to the VM to execute a write barrier. This is necessary for all objects that are not linked into one global table, i.e. everything except thinkers and class types. - always use the cheaper LOS opcode for reading pointers to classes and defaults because these cannot be destroyed during normal operation. - removed the pointless validation from String.Mid.

- fixed: State labels were resolved in the calling function's context instead of the called function one's. This could cause problems with functions that take states as parameters but use them to set them internally instead of passing them through the A_Jump interface back to the caller, like A_Chase or A_LookEx. This required some quite significant refactoring because the entire state resolution logic had been baked into the compiler which turned out to be a major maintenance problem. Fixed this by adding a new builtin type 'statelabel'. This is an opaque identifier representing a state, with the actual data either directly encoded into the number for single label state or an index into a state information table. The state resolution is now the task of the called function as it should always have remained. Note, that this required giving back the 'action' qualifier to most state jumping functions. - refactored most A_Jump checkers to a two stage setup with a pure checker that returns a boolean and a scripted A_Jump wrapper, for some simpler checks the checker function was entirely omitted and calculated inline in the A_Jump function. It is strongly recommended to use the boolean checkers unless using an inline function invocation in a state as they lead to vastly clearer code and offer more flexibility. - let Min() and Max() use the OP_MIN and OP_MAX opcodes. Although these were present, these function were implemented using some grossly inefficient branching tests. - the DECORATE 'state' cast kludge will now actually call ResolveState because a state label is not a state and needs conversion.

This is necessary for all objects that are not linked into one global table, i.e. everything except thinkers and class types. - always use the cheaper LOS opcode for reading pointers to classes and defaults because these cannot be destroyed during normal operation. - removed the pointless validation from String.Mid. If the values are read as unsigned the internal validation of FString::Mid will automatically ensure proper results.

- fixed: State labels were resolved in the calling function's context instead of the called function one's. This could cause problems with functions that take states as parameters but use them to set them internally instead of passing them through the A_Jump interface back to the caller, like A_Chase or A_LookEx. This required some quite significant refactoring because the entire state resolution logic had been baked into the compiler which turned out to be a major maintenance problem. Fixed this by adding a new builtin type 'statelabel'. This is an opaque identifier representing a state, with the actual data either directly encoded into the number for single label state or an index into a state information table. The state resolution is now the task of the called function as it should always have remained. Note, that this required giving back the 'action' qualifier to most state jumping functions. - refactored most A_Jump checkers to a two stage setup with a pure checker that returns a boolean and a scripted A_Jump wrapper, for some simpler checks the checker function was entirely omitted and calculated inline in the A_Jump function. It is strongly recommended to use the boolean checkers unless using an inline function invocation in a state as they lead to vastly clearer code and offer more flexibility. - let Min() and Max() use the OP_MIN and OP_MAX opcodes. Although these were present, these function were implemented using some grossly inefficient branching tests. - the DECORATE 'state' cast kludge will now actually call ResolveState because a state label is not a state and needs conversion.

- allow the VM to run on one global stack per thread. It is utterly pointless to require every function that wants to make a VM call to allocate a new stack first. The allocation overhead doubles the time to set up the call. With one stack, previously allocated memory can be reused. The only important thing is, if this ever gets used in a multithreaded environment to have the stack being declared as thread_local, although for ZDoom this is of no consequence. - eliminated all cases where native code was calling other native code through the VM interface. After scriptifying the game code, only 5 places were left which were quickly eliminated. This was mostly to ensure that the native VM function parameters do not need to be propagated further than absolutely necessary.

- added some syntactic help to the ZScript parser to allow defining the arrays with native structs on the script side instead of having to define them internally.

- fixed variable size mismatch and some warnings for 32 bit builds.

static const FieldDesc VMGlobal_##name = { "", #name, (size_t)&name, (unsigned)sizeof(name), 0 }; \
- added a dummy struct named '_' to define global variables. This can only be used internally. This method was chosen because it avoids adding variable declarations to the global namespace which would have required a lot more work while polluting the grammar. This way the global variables can be handled by a small bit of special coding in the struct generator.

class AActor;
- started with cleanup and separation of DECORATE code. * everything related to scripting is now placed in a subdirectory 'scripting', which itself is separated into DECORATE, ZSCRIPT, the VM and code generation. * a few items have been moved to different headers so that the DECORATE parser definitions can mostly be kept local. The only exception at the moment is the flags interface on which 3 source files depend.
2016-10-12 17:22:33 +00:00
- stop using the ATAGs for checking pointer types in asserts. This is an incredibly costly way to do a debug check as it infests the entire VM design from top to bottom. These tags are basically useless for anything else but validating object pointers being passed to native functions (i.e. mismatches between definition and declaration) and that simply does not justify a feature that costs execution time in non-debug builds and added memory overhead everywhere. Note that this commit does not remove the tags, it only discontinues their use.

// Standard parameters for all action functions
- use the function defaults from the script instead of explicitly setting them again in the code. This is a needless cause of potential errors and since the values are readily available now it's better to use them in the functions. - fixed: ZCCCompiler did not process array access nodes. - fixed: Function argument names were not placed in the destination list by the compiler. - scriptified several trivial functions from p_actionfunctions.cpp.

PARAM_OBJECT_NOT_NULL (self, AActor); \
- corrected the export signatures of several script exports to contain the correct classes, so that the fudging in FindFunction could be removed. - fixed PARAM_ACTION_PROLOGUE to assign correct types to the implicit pointers. It gave the actual class to the wrong one, which until now did not matter because all functions were using 'Actor', regardless of actual class association. - fixed the definition of IceChunk and removed some redundant code here. Since A_FreezeDeathChunks already calls SetState, which in turn calls the state's action function, there is no need to call it again explicitly.
2016-12-02 17:52:58 +00:00
PARAM_OBJECT (stateowner, type) \
- scriptified A_FatAttack*. - swapped parameters of two-parameter VelToAngle method, so that internal and script version are in line. - fixed parameter asserts to handle NULL pointers properly.

// for structs we cannot do a class validation
- scriptified the pistol to test if struct member functions work. - made APlayerPawn::PlayAttacking(2) virtual script functions so that mods have better control over player animations. Note that these have no native base so they skip the templated interface for managing virtual functions.

Using local static variable init directly results in hideous code for the need of being thread-safe (which, even if the engine was made multithreaded is not needed here.) * Importsnt node here: Apparently passing an actor pointer to the VMValue constructor results in the void * version being called, not the DObject * version.

FString FStringFormat(VM_ARGS);
- separated the code generation from the DECORATE parser and cleaned up the interface to the code generator. Most importantly, the VMScriptFunctions are now preallocated when being added to the list of functions to compile and will be filled in later by the code generator. This allowed the removal of some ugly maintenance code.
